I.V. stand and attachments

Abstract

An I. V. stand is provided for (1) use by itself; (2) releasable use with a wheelchair providing for movement of its supporting wheels to provide only swiveling wheels; and (3) use with a gurney providing an adjustable arm attachment. The I. V. pole has an indicator for showing the position of a snubber, or attachment, mechanism used to contact the wheelchair. The I. V. stand has two castered forward wheels and two non-pivoted rear wheels with a castered fifth wheel located between the rear wheels for lifting the rear wheels off a floor when all castered wheels are desired on the I. V. stand.

We claim: 
     
       1. An I. V. stand having an upstanding pole, a base, holding means on the pole for supporting medical objects, said base having five wheels, two of said wheels mounted on the front of said base for supporting said stand, two of said wheels mounted on the rear of said base for supporting said stand, said wheels mounted on the rear of said base being stationary, a fifth pivoted wheel having caster mounted on the rear of said base between said two stationary wheels, an extending and retracting mechanism for moving said fifth pivoted wheel downwardly to an extended position below said two stationary wheels for supporting said stand and moving said fifth pivoted wheel upwardly to a retracted position above said two stationary wheels for removing its support of said stand. 
     
     
       2. An I. V. stand as set forth in claim 1 wherein said extending and retracting mechanism has a foot operated mechanism for extending said fifth pivoted wheel downwardly to an extended position. 
     
     
       3. An I. V. stand as set forth in claim 2 wherein said foot operated mechanism provides means for holding said fifth pivoted wheel downwardly in its extended position when placed in that position. 
     
     
       4. An I. V. stand as set forth in claim 3 wherein said foot operated mechanism provides means for releasing said fifth pivoted wheel to be spring biased upwardly to its retracted position. 
     
     
       5. An I. V. stand having an upstanding pole means, a base, attachment means on said base for releasably attaching said I. V. stand to the rear of a wheelchair for movement therewith, said attachment means comprising holding flange means being movable outwardly on each side of said base for contacting a wheelchair to secure the I. V. stand to a wheelchair. 
     
     
       6. An I. V. stand as set forth in claim 5 wherein said base includes a housing, said housing being open on each side, said attachment means being located in said housing, said attachment means being movable to extend said holding flange means from the open sides of said housing to engage a wheelchair, said attachment means being movable by turning said pole means. 
     
     
       7. An I. V. stand as set forth in claim 6 wherein said attachment means includes a slide means on each side of said pole means in said housing, each slide means having an actuating member for moving each slide means outwardly to an extended position or inwardly to a retracted position, a cam means for moving said slide means outwardly, spring means for moving said slide means inwardly, means connecting said cam means to said pole means. 
     
     
       8. An I. V. stand as set forth in claim 7 including indicator means on said pole means to indicate the position of the attachment means. 
     
     
       9. An I. V. stand as set forth in claim 5 wherein said base has two rear non-pivoted wheels for supporting the rear of the base for straight movement, a swiveled wheel having caster, means mounting said swiveled wheel having caster between said two rear non-pivoted wheels for being extended to be below said non-pivoted wheels so that the swiveled wheel supports the rear of said base for movement in any direction or for being retracted to be above said non-pivoted wheels so that the non-pivoted wheels support the rear of said base. 
     
     
       10. An I. V. stand as set forth in claim 5 wherein said base has two rear non-pivoted wheels for supporting the rear of the base for straight movement, a swiveled wheel having caster, means mounting said swiveled wheel having caster between said two rear non-pivoted wheels for being extended to be below said non-pivoted wheels so that the swiveled wheel supports the rear of said base for movement in any direction for use with a wheelchair. 
     
     
       11. An attachment device for attaching an I. V. stand to a patient conveyance, said device having a collar for attachment to a pole on an I. V. stand, two adjustable arms, each adjustable arm having two ends, each adjustable arm being pivotally mounted at one end to said collar for "up and down" movement, each adjustable arm having a universal joint on the other end, each universal joint being fixed to a connecting device, each connecting device having means for fixedly connecting it to said patient conveyance. 
     
     
       12. An attachment device as set forth in claim 11 wherein said collar has two pivotal joints spaced approximately 90° apart around the collar, said pivotal joints being mounted for "up and down" movement for said adjustable arms.
